Hunting for supermassive black holes in nearby galaxies with the Hobby-Eberly Telescope. (2015)

Abstract:We have conducted an optical long-slit spectroscopic survey of 1022 galaxies using the 10m Hobby-Eberly Telescope (HET) at McDonald Observatory. The main goal of the HET Massive Galaxy Survey (HETMGS) is to find nearby galaxies that are suitable for black hole mass measurements. In order to measure accurately the black hole mass, one should kinematically resolve the region where the black hole dominates the gravitational potential. For most galaxies, this region is much less than an arcsecond. Thus, black hole masses are best measured in nearby galaxies with telescopes that obtain high spatial resolution. The HETMGS focuses on those galaxies predicted to have the largest sphere-of-influence, based on published stellar velocity dispersions ...(more)

The HET Massive Galaxy Survey (HETMGS) ran from 2010 April to 2013 August. The total survey consists of 1022 galaxies, with 1265 long-slit spectra taken over 550hr with the Hobby-Eberly Telescope (HET). All the observations were taken with the Marcario Low Resolution Spectrograph (LRS; in 4200-7400{AA} range). The typical spatial resolution of the observations is 2.5" FWHM.
